IMPROVEMENT-IN FLAT OR SAD-IRONS.

The Schedule referred to in these Letters Patent an'd making part of the same B' the handle of the flat-iron, its hardened bottom being represented at a by the shade-lines of the figure.

A flat-iron so made will seldom wear or become scratched on its smoothing-surface, and may be subbottom.

Lam aware that it is not new to harden a surface of cast-iron by casting the metal against 'Cilliilll a mold, railway-wheels having been so made, and therefore I make no claim to such, in the abstract.

Nor do I claim a fiat iron as ordinarily made, viz: withoutany hardening of its bottom by means as de scribed.

I claim' as a new or improved article of manufac ture l A flat or snd-i1on,made with the bottom of its body cast againsta chill-plate, and subsequently polished LUTHER LINCOLN.
